Hey Jack, good question. I don’t know how much you are going to pay for the pressure pot, maybe $175? Are you just using it for one build? The pressure pot is used to take the air bubbles out of the resin, in my case my resin starts setting up within 2 minutes, sometimes I don’t even get it poured out of the cup into the mold before it turns solid. You would need to use a really slow curing resin. Silicone for molds and resin aren’t cheap. Some of the decorations I still have to use the supplied metal parts (the cannons) for one, I won’t know what else till I try. One thing I can tell you is it will be a big investment.
